1o all to from it may concern:

Be it known that I, .losnrrr FossnL, of

`Grafton, in the county of Vorcester and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Combing Machines, of whichthe following is a specification.

My invention relates to an improvement in combing machines of the character described in Letters Patent of the United States No. 1,351,076, granted on the application of Harry Tunstall August 31, 1920, and it relates more particularly to the means for oscillating the nipper frames whereby each frame will normally-take exactly the same period of time to move from its point of rest to its detaching rolls and back, thus enabling` the two sides of the comber, when operating on the same grade of cotton7 to turnr out products of the same grade and with a substantially equally small amount of waste.

In combing machines of the Hellman type thecombing cylinder is set in a particularv position on its shaft and the movements of the nippers and the piecing-up or detaching rolls are timed so thatv they may cooperate properly therewith. In a machine like that described in the patent above referred to in which a plurality of combing heads are setback to back and arranged to be operated by a single operating unit, a combing cylinder and detaching rolls are provided for each nipper mechanism, each combing cylinder being mounted as shown in the said patent on a constantly rotating shaft 63 and the detaching rolls being oscillated by mechanism connecting them with shaft 63 through a gear system comprising gears 114i, etc., and a clutch. The nipper mechanisms are oscillated alternately and the combs and detaching rolls are set to be operated in opposed relation to each other. The means for oscillating the nipper mechanisms, as shown in that patent, comprises a lever 12 hung on the shaft 13 and swung by connections including a crank pin 10 on disk 9. rlhis results in an approximately accurate motionbeing given to the bowl 37 carried by the rocker arm 36 fast on shaft 13, which bowl as the shaft is rocked engages alternately the nippers 32 and oscillates them.

In view of the minuteness of the cotton fibre it is necessary, however, that each Specification of Letters Patent. lpgttglmitgd Emmy 23: M3922,

Application filed January 15, 1921.

Serial No. 437,423.

nipper frame in turn should arrive at its outward position at the moment when the comb on that side of the machine has reached a predetermined point in its movement, and the detaching or piecing-up rolls are at a particular position in their cycle of operations. It has been found that the connect-ions between the crank pin and the shaft 13 for operating the two sides of the machine are not sufficiently accurate always to produce on each side of the machine a product of equal value, because the piecing on both sides will not be equally good without reorganizing the machine or using a. different timing for the detaching rolls on one side from the timing of those on the other side.

My invention relates to means other than those shown in the said Letters Patent connecting the power shaft with the bowl 3T whereby a more accurate result will be accomplished and it will be understood by reference to the drawings where it is shown in its preferred form.

Figure 1 is a cross section of a head such as is shown in the said patent and embodying my invention.

Fig. 2 is a longitudinal detail` showing my improved mechanism and its connections in enlarged side elevation.

Figs. 3 and l are enlarged sections on lines 3 3 and l-l of Fig. l.

As the machine as a whole is fully described in said Letters Patent, l shall not describe it in detail. except in so far as it is necessary to point out my improvement in its preferred form.

In the drawings V13 is the shaft to be rocked. lt carries near each end an arm 36 at the lower end of which is the bowl B7. One only of these arms is shown 32 are the nipper frames which are engaged by the bowls 37 on the y supports B, E, which carry two parallel rods C tast thereto to serve as guidesefiior the carriage D. rlhis carriageV comprises four sleeves Z connected together so that the carriage may be reciprocated horizontally across themachine. The carriage D has vertical ways D1 .in which is mounted a block D2 with a hole through it in which ylies the crank pin l0. rihis construction is such that as the crank disk 9 rotates, carrying` with it the crank pin l0, the block D2 will slide vertically as occasion requires in the ways D1 while the horizontal movement ot the crank pin l() will cause the carriage to travel horizontally on the rod C. In order that this movement may be applied to the pendulum lever 12, the carriage D carries a pin E tree to turn in a block El vhich slides vertically in the 'torked end e ot the lever l2.

Thus the rotation of the crank disk 9 will cause a lateral swinging or oscillating movement to be given to the lever l2 and shaft 18,-a movement which is positive and which has positive limitations and consequently gives a positive outward movement to the nipper trames, allowing each in turn to swing back into its vertical position in which position its screw 321 engages the stop 642.

Z1 and el are openings for lubrication.

lhile I have described above the simplest method of accomplishing thedesired result, l do not mean to limit myself to the precise construction shown, the purpose of which is to secure a positive means whereby in a duplex comber ot this class the nipper frames on both sides ot' the machine may be timed to co-operate with the combs with equal precision so that there will be turned out l'rom the heads on both sides of the machine a product ot' equal character in all respects and tor this purpose give to each nipper frame on both sides ot the machine a movement which shall be equal both in point of time and extent with every other.

that l claim as my invention is l. ln a machine of the kind described, in combination with the nipper mechanisms, means ttor operating them alternately comprising a rock shaft, an arm mounted to Vrock therewith and adapted to engage and operate said nipper mechanisms, and means for rocking said rock shalft comprising a, crank disk, crank pin thereon, a pendulum lever mounted on said rock shal't, and means connecting said crank pin and said pendulum lever whereby said lever will be given an oscillation equal in regard to time and amplitude in each direction about said rock shaft.
